Question 263507: A flash of Lightning is seen, and the resulting thunderclap is heard 3 seconds later. If the speed of sound averages 1,100 feet per second, how far away is the storm?

I solved this problem like this: 1100=1 sec
x= 3 sec
1100(3)= 1x
3300=1x
x= 3300 ft away is the storm.
Is this correct?

You've got it.
.
But it might be best to think of it terms of the distance equation.
.
d = rt, where d=distance, r=rate, t=time
.
d = 1100 ft/sec * 3 sec
.
d = 3300 ft
.
Note the 'seconds' cancel, so the answer is in 'feet.'
Units of measure are important. And if you keep track of the units, you sometimes can figure out how to solve the equation to get an answer in the correct units.
.
Good luck.
